Building HACMP

www.unixbabuforum.inI like to know the steps to build hacmp cluster (2 node). It would be on p570. Its expected to be an active-pasive cluster. 
I have limited knowledge on hacmp and i need to build it quickly as demanded by customer. I do not have time to read much. Hacmp ver 5.5 would be used across lpars.
www.unixbabuforum.inHACMP is not like installing a small piece of software and you are done. I 
spent 3 weeks reading thru manuals online searches and was able to finally 
make it working. First plan what you type of HA you want. build servers, 
install HACMP configure HA , test is thoroughly and then implement it in 
production. If these are vioclients then all the vgs have to be in Enhanced 
concurrent mode. the cookbook for HA 5.5 is available online. 
Please start reading and building the HA - prior to that, decide which way 
you want. IPAT via aliasing or replacement. I used IPAT via aliasing thru 
etherchannel. If you get stuck somewhere then please post your questions. 
Don't get me wrong brother but you need to start helping yourself then 
someone will help when you get stuck. Please don't think I am trying to 
insult you. When I started as AIX admin i knew nothing not even how to 
create a user, but I made effort to search the web and forums and read books 
before asking how to do things. 


www.unixbabuforum.inKnowing the concept is essential for HACMP, both designing and implementing 
(even operating). It is worth you deny the request because you will get into 
trouble by managing a mal-designed cluster
